Need help drying - will ona gel work with one plant?

If there is one small plant, maybe an ounce or less, hanging upside down in a closet, would ona cover the smell for the short day period. Also, where would be the best place to put the ona? No other options because of slow flowering sativas taking up carbon filter, needy bitches. Do I need to worry about ona effecting smell?

Put the ona outside the closet, should be fine to cover the smell of one plant drying. Do not put the ona in with the bud or it'll end up infecting it with ona taint.

Make sure the ona is a good distance from the weed

u never want the bucket near the plant other wise your weed can get a funny taste ..........keep the bucket high up/dresser lvl ( where the air flow is so spreads it around...ideal the warm air so it travels cools off sinks )

as for drying i found a near fool proof way
3x3x5 tent
1 carbon filter with 4 inch booster fan
2 axis fan (left and right up and down) ...great air movement
humidifier and dehumidifier ( keep it at 45-55)
quick dry rack 36" on it has 6 tiers but can only really use 4

with u clipping it and laying it out on the rack u get a move even dry .........so as long as the tent is keep at 45-55% RH in 7 days u have jar able stuff (can smoke or sell like that or can cure for 8 weeks)

a good dry is simple
temps below 80 but above 60 F
no light/as little as possible direct light
air movement
RH between 40-60% .........if it goes above 55% add on a anouther day to the dry time

with your plant upside down the water is being drawl to the top colas and let out there so the ones that are at the bottom/top of the upside down plant will dry before the top (big buds) at the bottom
(trying to cut those off before the tops are truly dry can lead to moldy bud when u jar it) u are looking at a good 10 11 day dry smokable after 8

keep the ona gel/block a good distance from the plants outside of your grow tent/room. i normally put it by the door to the room.

thanks for all the replies, appreciate it
